Netherlands Application July 14, 1952, Serial No. 298,684

4 Claims.

The present invention relates to a spindle for a spinning or twisting machine, and more particularly to a spindle provided at its free end with protruding members adapted to carry along a thread fed to the spindle and guided by same.

Such spindles are especially used in spinning methods where a balloon is avoided or at least suppressed. The main object of the invention is to provide a spindle of such construction that the thread when it breaks cannot wind itself between protruding members to form a confused mass, which cannot be easily removed from the spindle.

A further object of the invention is to provide a spindle which need not be combined with means for sucking away a broken thread.

According to the invention the protruding members overlap each other in axial direction of the spindle. By overlapping we mean that the centers of the protruding members are situated at dilerent points of the spindle axis, but that then there is still an overlap or interpositioning between certain parts of the protruding members, which for this purpose are of an elongated nature.

There may be several series of protruding members arranged one above the other. However, a very simple embodiment of the invention is only provided with two protruding parts mounted oppositely one another and being interposed partially with respect to one another in axial direction of the spindle.

In the drawing Figure 1 illustrates a known spindle head;

Figure 2 represents an example of a spindle head according to the invention;

Figures 3-8 illustrate other embodiments and Figures 9-11 are plan views of the spindles according to Figures 6-8.

In the known head according to Figure 1 there are two series of protruding members I and 2. Between these series or crowns there is an annular groove 3, which offers a retaining space to a broken thread, so that such a thread Will wind itself there around the spindle and form a confused mass 4.

This bad phenomenon is now avoided by means of the invention. I

According to all the shown embodiments the protruding parts la, 2a, Ib, 2b, Ic, 2c, Id, 2d, le, 2?, if, 2f, and Ig, 28, which serve to grip the thread fed to the spindle and to carry it along, overlap each other or are interposed by a distance s. Due to this simple measure the groove 3 between completely 2 the protruding parts is bridged and a broken thread cannot be gripped in a gap or a groove between the protruding members.

Figures 2-5 show embodiments in which there are a plurality of protruding members la, 2, lb, 2b, lc, 2c, and ld, 2d in each crown.

However, the number of protruding members may even be reduced to 2.

These embodiments are shown in Figures 6-11.

The protruding members may be at a slight angle with the longitudinal axis of the spindle as shown in Figures 3-5 and in Figures 8 and 11.

In al1 the figures the spindle itself has been marked with the number 5.

As shown in Figures 6 and '7 the two overlapping protruding members le, 2e, and If, 2f are mounted oppositely one another. The upper protruding members Ie and If here serve for properly gripping and carrying along the thread and the lower protruding members guide the thread which further on is guided on the spindle according to a helicoidal path having a very steep pitch. At the bottom of the spindle the thread is guided to a traveller (not shown) which runs on a spinning ring.

The spindles according to Figures 6-8 may be used at very high numbers of revolutions, e. g. 10,000 revolutions per minute and more.

According to Figures 7 and 10 the protruding members are simply made of a piece of curved wire, which is connected to the spindle head.

Having now described our invention and the object thereof, what We claim is: l 1. A spindle for a spinning or twisting machine provided with members protruding from the spindle surface near the upper end of the spindle and adapted to carry along a thread, said members being partially interposed with one another in longitudinal direction of the spindle.

2. A spindle according to claim 1, in which two protruding members are provided arranged at opposite sides of said spindle.

3. A spindle according to claim 1, in which the members are formed by curved pieces of wire.

4. A spindle according to claim 1, in which the members have an oblong shape and are arranged at an angle with the axis of the spindle.
